Filming an adaptation of an award-winning novel has started at an iconic Ceredigion building.

The Library Suicides, the debut feature film from award-winning director Euros Lyn, and based on Fflur Dafydd’s bestselling novel Y Llyfrgell, is an offbeat thriller, set in the National Library of Wales, Aberystwyth.

During one night shift, the twins set off on a murderous quest to avenge their mother’s death at the National Library of Wales, but are soon disrupted by night porter Dan (Dyfan Dwyfor), who is unwillingly caught up in the saga.

The Library Suicides is the third film to go into production from Ffilm Cymru Wales’ emerging talent scheme Cinematic.

Set up in partnership with the BFI Film Fund, BBC Films, Creative Skillset, Edicis, Soda Pictures and S4C the scheme supports emerging filmmaking talent from Wales.

The Library Suicides is the first of these to be filmed in the Welsh language. Soda Pictures have distribution rights in the UK and Ireland, and S4C will broadcast the film.

Euros Lyn said: “As a huge fan of the genre, I’m very excited to be making a thriller in Welsh and what better place to set it than the wonderfully atmospheric National Library of Wales in mysterious Aberystwyth?

“Wales now has a host of world class writers, actors and crew I’m very excited to be working alongside so many of them on The Library Suicides.”

Having worked on popular Welsh language programmes as well as Belonging, Lyn, who was born in Menai Bridge, has also directed episodes of Doctor Who, Torchwood, Last Tango In Halifax and Broadchurch.

“I first envisaged this idea as a film, but ended up writing a book instead. Bringing these characters to the big screen feels like a dream come true, and I feel very lucky to be working with such an incredibly talented director and a fabulous cast, who all bring their own unique vision to the project,” she said.

While the National Library of Wales at Aberystwyth has a significant national and international profile this is the first time it has opened its doors to such a project.

Avril Jones, Director of Collections, said: “The nature of our work and the profile of the building itself means we have many programme makers who come here to record but this is the first time a feature film has been set here.

“The architecture of the building naturally lends an aura of mystery to such a project and we very much look forward to seeing the completed film.”
